+# poezio emoji_ascii plugin
+#
+# Will translate received Emoji to :emoji: for better display on text terminals,
+# and outgoing :emoji: into Emoji on the wire.
+#
+# Requires emojis.json.gz (MIT licensed) from:
+#
+#     git clone https://github.com/vdurmont/emoji-java
+#     gzip -9 < ./src/main/resources/emojis.json > poezio/plugins/emojis.json.gz
+
+# TODOs:
+# 1. it messes up your log files (doesn't log original message, logs mutilated :emoji: instead)
+# 2. Doesn't work on outgoing direct messages
+# 3. Doesn't detect pastes, corrupts jabber:x:foobar
+# 4. no auto-completion of emoji aliases
+# 5. coloring of converted Emojis to be able to differentiate them from incoming ASCII
